In this one, a young couple is out in nowhere, and he whistles for a new dog for his loving wife (how did the dog get out there in nowhere-ville).
Then she tops that gift by showing him a horribly expensive GMC brand new truck, probably over $50,000 that she bought without telling him, that suddenly bursts over the horizon, which is driven by somebody, but we don't know who (probably her boyfriend that he doesn't know about).
Same ad they used LAST year. The girl still does that phony whistle.
